Unit 11 Oceans
Concepts of Earth Science
Key Concepts and Questions to Be Able to Explain and Answer:
1. Explain Archimedes’ principle and how it relates to buoyancy.
2. Describe the two theories for how Earth’s oceans developed.
3. List the common dissolved gases that are found in the ocean according to abundance. List
the common solids that are found in the ocean according to abundance. How does
temperature impact the amount of dissolved gasses and salinity?
4. How do salinity and temperature affect the density of ocean water?
5. How does ocean temperature change with depth?
6. Be able to identify and describe the features of the ocean floor.
7. What mineral and food resources can be extracted from the ocean?
8. Compare and contrast the formation and movement of surface and density (deep water)
currents.
9. Draw a picture to show how the water molecules in a wave move. Show how the energy of
the wave moves.
10. Describe the factors that determine the size of a wave: speed of wind, length of time the
wind blows and fetch.
